C ++，从字符串到stringstream到向量< int> [英] C++, Going from string to stringstream to vector<int>

问题描述

我有一个步骤的示例程序，我想在我的应用程序上实现。我想push_back分别在字符串上的int元素，成一个向量。我怎么能够？

I've this sample program of a step that I want to implement on my application. I want to push_back the int elements on the string separately, into a vector. How can I?

#include <iostream>
#include <sstream>

#include <vector>

using namespace std;

int main(){

    string line = "1 2 3 4 5"; //includes spaces
    stringstream lineStream(line);


    vector<int> numbers; // how do I push_back the numbers (separately) here?
    // in this example I know the size of my string but in my application I won't


    }

推荐答案

int num;
while (lineStream >> num) numbers.push_back(num);
